Evolution of Chordates. Another major step in animal evolution was the evolution of a notochord. A notochord is a rigid rod that runs the length of the body. It supports the body and gives it shape (see Figure below). It also provides a place for muscles to anchor, and counterbalances them when they contract.

Living things (even ancient organisms like bacteria) are enormously complex. However, all this complexity did not leap fully-formed from the primordial soup. Instead life almost certainly originated in a series of small steps, each building upon the complexity that evolved previously: 1. Simple organic molecules were formed. Simple organic molecules, similar to the nucleotide shownOrganic evolution are the events involved in the evolutionary development of a species. It means that all life descended from other life, although features may have changed dramatically along the way.Feb 21, 2019 ...
